I just bought a used 2005 Passat 2.0L TDI. I will soon need to change the oil. I looked for the oil types listed in the TDI forum, but can's seem to find the exact match. I found an oil from Mobil, (synthetic), called Turbo-Diesel, but it seems like it is meant more for trucks. It is rated CH-4. I went out to Mobil's website and looked up this product and found where someone had asked if this oil met VW 502.00 standards and the reply was no. Should I use this oil in my car?

Also, I found an oil called Mobil Delvac 1300, (synthetic), but the weight is 15w-40, not the 5w-40 recommended in the forum. This oil also had a rating of CH-4. I live in Alabama so I wonder if it is ok to use this weight oil since it never really gets that cold here? If both oils will work for my car, which would be the better choice?

Yes, people appear to be having good success with this oil even though it does not meet the spec for the car. (I'm assuming your warranty is long gone). Oil can be found at many Walmarts in gallon size containers. I think it's around $26 now. It's 5W40, Turbodiesel truck. The newest bottle looks a bit different compared to this one:
